Abstract

A new nanocomposite system based on gold nanoparticles and thiometalates is described. According to the metalate species, WS42¬ or WS2O22¬, and to the experimental conditions, two sizes of particles are obtained (d = 2 or 5 nm). These particles lead either to stable colloidal solutions or irreversible micrometric spherical aggregates of nanoparticles cemented by WS42¬. Energy dispersive spectrometry (EDS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), UV-vis spectroscopy and X-ray photoelectron spectroscopy (XPS) have been used to fully characterize the different composite systems.
